Our research interests have been focused on the design of new monomeric and polymeric materials using organoiron complexes as precursors. Cyclopentadienyliron chloroarene complexes were used to mediate the synthesis of sulfide contg. compds. These compds. were designed with various arom. and aliph. spacers. Oxidn. of the sulfides led to the isolation of the sulfone monomers with terminal chloro groups. These monomers were also subjected to sulfonation reactions to give their corresponding sulfonic acid salts in very good yields. Polycondensation of the monomers with diphenolic reagents led to the formation of the polysulfones as shown below. [on SciFinder(R)]
